Specifications include, but are not limited to: A. Geotechnical Investigation and Laboratory Testing: The selected proposer/offeror shall provide foundation and geologic/geotechnical exploration in accordance with the procedures, requirements and guidelines outlined in the latest edition of the New Mexico Department of Transportation (“NMDOT”) Geotechnical Design Guide (“Manual”). The geotechnical exploration and laboratory testing shall include at least the following: 1. For roadway, soil sampling and testing during construction the selected proposer/offeror shall represent the two (2) foot prism of finished subgrade. 2. For bridge elements, one (1) soil boring and/or rock core shall be completed at each abutment and each pier element. At the abutments the borings should be taken to a depth of eighty (80) feet. At the piers, the borings should be taken to a depth of hundred (100) feet. Lesser depths of exploration will be acceptable with the presence of bedrock or very dense soil strata. 3.
